Title: Right and left distribution control device for vehicle brake force
Inventor: MATSUDA TOSHIRO
IPC: B60T8/24
Filed: 1990-12-21
Abstract: PURPOSE:To prevent the occurrence of over-steering tendency during a vehicle's turn under a weak brake force, or under-steering tendency during the turn under a strong brake force by controlling the brake force for distribution to right and left. CONSTITUTION:A controller 18 adjusts the set load of pressure regulation springs 10L and 10R via the operation of motors 17L and 17R, when the turn of a vehicle is detected with a lateral acceleration sensor 20. The split points of right and left fluid pressure control valves 6L and 6R are thereby changed. Furthermore, the controller 18 maintains a split point related to a turning outer wheel higher than a split point related to an inner wheel under the application of a weak brake force, depending upon the deceleration of a vehicle detected with a longitudinal acceleration sensor 21. On the contrary, the split point related to the turning inner wheel is changed to be higher than the split point related to the outer wheel under the application of a strong brake force. According to this construction, a brake force for the outer wheel becomes larger than for the inner wheel during a vehicle's turn under a weak brake force, thereby generating yaw moment to offset over-steering tendency. On the other hand, yaw moment is generated to offset under-steering tendency under a strong brake force. As a result, a vehicle's turning locus can be properly maintained under the application of a brake force.
